To all whom it may concern:

Be it known that I, TIMUEL B. LANIER, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Steam or Hot'VVaterHeat-' ers, of which the following is a specification.

This invention relates to heating appara In the accompanying drawings,Figure l is a vertical sectional view through a heater embodying thefeatures of this invention. Fig.

2 is a vertical section on dotted line 2 2 of Fig. 1. Fig. 3 is ahorizontal sectional view taken on dotted line 3 3 of Fig. 1. Fig. 4is avertical section on dotted line 4 4 of Fig. 1.

In the construction of a heater embodying the features of my invention Iprovide a brickwork frame or casing, which casing is oblong inhorizontal section and comprises the front wall 1, the rear wall 2, theside walls a 3 and 4, and the top wall 5. A bridge 6 extends through thelower portion of the casing from side to side thereof, and between thisbridge and the front wall 1 are suitably supported the grate-bars 7.Access to the ashpit 8 beneath the grate is had through an opening 9,formed in the front wall 1, which opening is closed by a door 10. Anopening 11, closed by a door 12, provides access to thecombustion-chamber 13. 14 and'15 are cleaning-openings formed in thefront wall 1 and the side wall 4, respectively, said openings beingclosed by suitable doors 16 and 17.

Directly above the combustion-chamber 13 is a box-coil 18, comprising aplurality of pipes 19, which pipes areconnected in continuous verticalseries by the return-bends 20. The vertical series of pipes 19 areunited at their lower rear ends by the header 21 and at their upperforward ends by the header 22. Pipes 23 and 24, communicating with opposite ends of the header 21, extend through suitable openings in the sidewalls 3 and 4.

Connected with opposite ends of the header 22 are pipes 25 and 26, alsoextending through said side walls. These pipes 23, 24, 25, and 26support the box-coil 18 within the brickwork casing. A blow-off pipe 27,extending through the rear portion of the brick setting, communicates atone end with the pipe 24 and at its other end with the pipe 23, onebranchof the T that joins the pipes 23 and 27 being closed by a plug 28,which plug is removed when it is desired to flush out the heater. Anintake-pipe 29 also communicates with the pipe 23, said intake-pipebeing provided with a cutoff valve 30. A return-pipe 31 is connectedwith the intake-pipe 29 at a point between the valve and the point ofjuncture of said intake-pipe with the pipe 23.

Above the box-coil 18 is another similar box-coil 32, comprising thepipes 33, connected in continuous vertical series by the returnbends 34.The vertical series of pipes 33 are joined at front and rear by theheaders 35 and 36. Short pipes 37 and 38 communicate with oppositeendsof the header 35, and similar pipes 39 and 40 are connected withopposite ends of the header 36, said pipes 37, 38, 39, and 40 passingthrough suitable openings in the side walls 3 and 4 and supporting thebox-coil 32 within the casing of the heater. The pipe 25 from one end ofthe header 22 of the lowerbox-coil 18 is connected through the pipe 41with the pipe 37 from the lower header 35 of the upper box-coil 32. Apipe 42 connects the pipe 26 from the opposite side of the header 22with the pipe 38 from the header 35. The outer ends of the pipes 39 and40are connected, by means of pipes 43 and 44, with a pipe 45, extendingacross the front of the heater. The pipe 45 is provided with anair-valve 46.

47 refers to a storage tank or drum located above the upper box-coil 32,the forward'end of said tank projecting through and being supported inan opening 48 in the front wall 1 of the heater. The rear end of saidtank is supported upon a bar '49, having its ends seated in recesses 50in the side walls 3 and 4. The upper portion of the drum is connectedwith the pipe 45 through a pipe 51, which latter pipe is provided with acut-0E valve 52. The lower portion of the drum communicates with eachend of the lower header 21 of the lower box-coil 18 by means of thedownflow-pipes 53. The tank 47 is provided with the usual water-gage 54,and from its upper portion extedds the service-pipe 55, communicatingwith the radiators or other apparatus to be supplied with steam or hotWater.

In order that the products of combustion shall pass entirely through thetwo box-coils -18 and 32 and beneath the entire length of thestorage-tank 47, I support in any suitable manner two baffle-plates 56and 57, the plate 56 extending between the two box-coils from the frontWall 1 to the rear end of said coils and the other plate extendingbetween the upper coil 32 and the tank 47 from the rear Wall 2 to withina short distance of the front wall lthereof. A smoke-flue 58 is provided between the rear wall 2 and the rear end of the drum 47, the upperend 'of said smoke-tlue communicating in any convenient manner with thesmoke-stack or chimney.

When the apparatus hereinbefore described is to be operated as ahot-water heater, water is admitted to the heater and the communicatingcirculating-pipes of the heating system through the intake-pipe 29. Whenthe proper amount of water has been admitted, the supply is cut off bymeans of the valve 30. The flame and furnace-gases sweep through thebox-coils 18 and 32 and beneath the storage-drum 47, passing out of theheater through the smoke-flue 58. The heated water passes from the lowerbox-coil 18, through the pipes 41 and 42, to the upper box-coil 32 andfrom said upper coil into the storage-drum 47 through the pipes 43, 44,45, and 48. From said drum it passes through the service-pipe 55 to thecirculating system of the building, returning to the lower boxcoil 18through the return-pipe 31. The downflow-pipes 53 facilitate the freecirculation of water through the box-coils 18 and 32 and the tank 47.

The operation of the heater when used to generate steam is substantiallythe same as when used for hot-water heating, except that only sufficientwater is admitted through the intake-pipe 29 to fill the box-coils 18and 32 and to partially fill the drum 47.

.The apparatus herein illustrated and described is susceptible of manymodifications in the form and arrangement of its parts without adeparture from the spirit and scope of my invention, wherefore I do notlimit myself to the particular construction herein set forth.

I claim as my invention 1. In a steam or hot-water heater, incombination, two box-coils supported one above the other; means ofcommunication between the upper portion of the lower coil and the lowerportion of the upper coil; a service-pipe communicating with said upperbox-coil; and a return-pipe communicating with the lower portion of thelower box-coil.

2. In a steam or hot-water heater, in combination, two box-coilssupported one above the other; means of communication between the upperportion of the lower coil and the lower portion of the upper coil; astoragetank supported above said coils; means of communication betweenthe upper portion of the upper coil and the upper portion of said tank;means of communication between the lower portion of the tank and thelower portion of the lower coil; a service-pipe communicating with theupper portion of said tank; and a return-pipe communicating with thelower portion of the lower coil.
